Welcome to the family! The constitution of the chiral D(2)-C(80) fullerene has been confirmed through single-crystal X-ray analysis of the chlorinated C(80)Cl(12). The addition pattern of the chlorine atoms in the structure of C(80)Cl(12) together with other structures of halogenated higher fullerenes is discussed. A stepwise principle of higher fullerene reactivity is proposed. Unusual short intermolecular chlorine-chlorine contacts are reported.
